1 Claim.

This invention relates to a vaginal syringe essentially adapted for thepractice of feminine hygiene and has for an object the construction of adevice of the character described which i shall be efficient inoperation and made of the minimum number of parts, such parts beingseparable for the cleaning of the device, to insure sanitation thereof.

With reference to the accompanying drawing, forming a portion of thisspecification.

Figure 1 is a vertical elevation of the entire device;

Fig. 2 is a side view of the nozzle portion, showing certain parts inseparated relation;

Fig. 3 is a vertical section, enlarged, of a portion of Fig. 1; and

Fig. 4 is a section on line 4-4 of Fig. 3.

The numeral 5 designates the usual rubber bulb for the reception,discharge and withdrawal of the douche liquid. In the open end of thebulb 5 is positioned a hollow hard rubber nipple 6 provided with flanges7 and 8 which engage the upper and lower surfaces of a collar 9 formedin the bulb 5. The nipple 6 has an exteriorly threaded extension 10carrying a loose washer 11 of rubber or other flexible material.

The nozzle of the device comprises a barrel 12, of hard rubber orsimilar material, interiorly screw threaded at 13' for removableengagement with the threaded portion 10 of the nipple 6. Barrel 12 has acentral bore 13 which, when the device is completely assembledcommunicates with the hollow bore of nipple 6. A circumferential flange14 is provided for a pur- -pose hereafter explained.

For a portion of its length the barrel 12 is continued of the sameexternal diameter, such portion being slidably engaged by the usual stophood or shield 14 having a central aperture 15 engaging the barrel.

Beyond the portion referred to the barrel 12 is provided with three ormore openings 16 of generally oval shape having side walls 17 inclinedtoward the bore 13, such walls terminating in exterior ribs 18 ofslightly larger diameter than the barrel 12 for the purpose of exertinga dilating pressure against the walls of the part to be cleaned by thedevice. Beyond the openings 16 the barrel 12 is interiorly threaded at19.

' Formed to snugly fit within the bore 13 of the barrel 12 but slidableand rotatable therein is a member 20 of hard rubber or like materialhaving a central bore 21 and being perforated as ishown at 22 by aseries of forwardly inclined apertures. The member 20 is exteriorlythreaded at 21 for engagement with the threaded portion 19 andterminates in a rounded head portion 23. The bore 21 extends up into thehead 23 as shown and from such bore to the outer periphery of the head23 are provided ducts 24 also forwardly inclined.

Although formed to be readily removable by sliding engagement With thebore 13 the member 20 is carefully machined to form a fluid tightengagement with such bore 13 and the engaging threads 20 and 21 formedso that upon the tightening of the member 20 by rotation thereof, theperforations 22 will coincide with the openings 16.

In assembling the device the member 20 is inserted within the bore 13 ofthe barrel 12 as shown in Figure 2 with the two sets of threads 19 and21 in engagement whereby rotation of the member 20 by means of the head23 will cause such member to seat itself within the bore 13 with theperforations 22 in alignment with the opening 16 in the member 12. Themember 12 is then connected to the bulb 5 through the medium of thethreaded portions 10 and 13, being tightened against the washer 11 inorder to form a liquid tight joint.

In operation the bulb 5 is filled with the douche liquid in the usualmanner and the nozzle portion of the device inserted in the part to becleansed. By pressure upon the bulb 5 the douche liquid is forcedthrough the hollow nipple 6 and into the bore 13 thence through the bore21 and outwardly through the perforations 22 and the ducts 24. inforwardly inclined small streams adapted to impart a powerful cleansingaction upon the walls of the vagina.

The depth of insertion of the device is governed by the stop hood orshield 14 which is slidable along the member 12 between the flange 14and the ribs 18.

The douche liquid is removed from the vagina by permitting the bulb 5 toexpand whereupon the douche liquid is retracted through the ducts 24 andthe perforations 22 through the bores 21 and 13 into said bulb 5.

For the purpose of cleaning the device to insure sanitation the member20 may be unscrewed from connection with the barrel 12 and removedaxially therefrom as shown in Figure 2 and the barrel 12 may be removedfrom connection with the bulb 5 by unscrewing from the threaded portionof the nipple 6 whereby all surfaces may be presented for sterilization.

Having described my invention, what I claim A device of the classdescribed comprising a single hollow barrel having an imperforateportion attachable at one end to a compressible bulb, said barrelforwardly of said portion having a plurality of external, longitudinal,relatively narrow ribs projecting radially outward beyond the peripheryof the said portion defin ing between them a series of elongatedopenings communicating with the bore of the tube, a tube memberremovably disposed in said bore extending from the forward end of saidbore to a location past said openings and at said location being inintimate engagement with the wall of said bore, a substantiallysemi-spherical head .therethrough from the interior of the tube, the

bores of said barrel and said tube constituting the sole passageway inthe device to and from the bulb and said openings.
